Important note
This lab firmware is a beta version. We tested the software in standard environments before making it available to the public, but it may still result in malfunctions. AVM will not be liable for any damages that arise from the use of the lab version.

As you can see the IPv6 support is extensive and will most likely provide you with the kind of IPv6 connectivity you need.

The download link for the beta firmware is on the IPv6 lab website and can be found for the 2 currently supported models the 7270 (ADSL2+) and the 7570 (VDSL)
